In addition to the other post with the "how", here is an example that does it to a file using SPLIT and GZIP to get n 500meg compressed files (where n varies depending on the size of the export)....
It exports the whole database and then does an import to test the integrity of the export file as much as possible (also shows how to reimport this munged up file)...
#!/bin/csh -vx
setenv UID sys/o8isgr8
setenv FN exp.`date +%j_%Y`.dmp.gz
#setenv FN exp.`date +%j_%Y`.dmp.Z
setenv PIPE /tmp/exp_tmp.dmp
#setenv COMPRESS compress
setenv COMPRESS gzip
echo $FN
cd /nfs/atc-netapp1/expbkup2
ls -l
rm expbkup.log export.test exp.*.dmp.{gz,Z}.* $PIPE mknod $PIPE p
date > expbkup.log
$COMPRESS < $PIPE | split -b 500m - $FN. &
exp userid=$UID buffer=20000000 file=$PIPE full=y >>& expbkup.log
date >> expbkup.log
date > export.test
cat `echo $FN.* | sort` | zcat > $PIPE &
imp userid=sys/o8isgr8 file=$PIPE show=y full=y >>& export.test
date >> export.test
ls -l
rm -f $PIPE
